select2 cant generate route

[thechoiceone]

Hi, im following this https://github.com/avocode/FormExtensions/issues/22 to get select2 field in my form but im getting this error:

Notice: Undefined property: Acme\DemoBundle\Form\Type\Demanda\NewType::$router in C:\xampp\htdocs\gestion\src\Acme\DemoBundle\Form\Type\Demanda\NewType.php on line 29

Fatal error: Call to a member function generate() on a non-object in C:\xampp\htdocs\gestion\src\Acme\DemoBundle\Form\Type\Demanda\NewType.php on line 29

im using newType instead of editType but im getting the same if i puth the code in edit, here is my NewType.php

<?php //src/Acme/DemoBundle/Form/Type/Demanda/Newtype.php namespace Acme\DemoBundle\Form\Type\Demanda;

use Admingenerated\AcmeDemoBundle\Form\BaseDemandaType\NewType as BaseNewType; use Symfony\Component\Routing\Matcher\UrlMatcher; use Symfony\Component\Routing\RequestContext; use Symfony\Component\Routing\RouteCollection; use Symfony\Component\Routing\Route; use Symfony\Component\HttpFoundation\Request; use Symfony\Component\DependencyInjection\Container;

/**

• NewType */ class NewType extends BaseNewType {

  protected function getFormOption($name, array $formOptions) { if ($name === 'cliente') { $formOptions = $this->getClientes($formOptions); }

  return $formOptions;

  }

  private function getClientes($formOptions) { $ajax = '{ url: "' . $this->router->generate('queryClientes') . '", //here is the problem dataType: "jsonp", quietMillis: 100, data: function (query, page) { return { query: query, limit: 10, page: page, }; }, /more code ..../ }

my field in generator.yml cliente: label: Cliente getter: cliente.nombre filterOn: cliente formType: afe_select2_entity

im stuck with this becouse my json response is workin good in i dont have how to try,

im also have replaced the $this->router->generate('queryClientes') whit the route and this show almost all the form, but not show the select2 field.

ty for your time guys and good luck
